If the one is full anery and the other is 100%het albino what are the chances of a snow? If any? From what I have been reading a snow is anery/albino. so if both genes are represented I wonder what the chances are. sorry if I sound ignorant to the genetics but I am very new to this and just want to understand more.

They will each donate a gene which will make them all het for anery and 50% possible for het albino. If you get 2 double hets and breed them togerther you can get some snows.

so basicly i would have to aquire an albino and breed it to and anery to get a DH Snow? or do you mean if hypotheticly breed the offspring of an anery x 100% het albino ? let me see if i get this right, anery x het albino = 100% het anery 50% het albino, is that the same as DH snow? sorry to be a nag but im still trying to understand the whole DH thing.
No, anery X het albino is het anery 50% het albino, that means that they have a 50% chance of being double het for snow. When you breed a het to an animal that does not carry the gene, half the babies are het and half not. That is where the 50% het comes in. I suggest going to Pete Kahl's website he has punnet's squares made up with all of this. Vey good site for learning how genetics work.

ok i think i understand now
50% of offspring = DH snow &
50% of off spring = het anery , 50% het albino? or am i still not getting this? i tried that and it is pretty vauge. and if i am right on above how do you tell the DH snow from the others or is it trial and error?

I don't think you quite have the idea yet. If you breed an Anery to a 100% het for Albino you will get a litter that is 100% het for Anery. The entire litter will also be 50% "possible" het for Albino. That does't always mean that 50% of the babies will actually be het for albino or Double het for Snow. Rather it means that "each baby" has a 50% chance of being het for Albino. At least, that's the way I understand it. Either way they will all carry the Anery gene. The only way to be 100% sure and to get 100% double het for snow (anery + albino) is to breed an Anery to an Albino.
If you're breeding Anery to 100% het for albino that will make the entire litter 50% "possible het" for snow and/or 100% het for anery. All the babies will look normal, but will carry the recessive gene or genes. I've pretty much confused myself here, so I hope I haven't confused you too. LOL.

linda, no not at all it makes perfect sence now. i went to PK web site and i couldnt find possible out come of a DH snow xDH snow. would you happen to know what that is? all it showed was DH snow x snow. and others of course but no DH snow x DH snow.

I'm not very good with this, but I'll try. If you breed DH snow to DH snow you would get.........
A snow boa if you're lucky. It doesn't always work out that way. Of course, some people get more than 1.
You "should" get Albinos and Anerys.
You'll also get some "normal looking" boas.
If you get a Snow boa it will carry both Anery and Albino genes.
If you get Albinos they have a 66% chance of carrying the Anery gene. The Albinos would be Albino 66% Possible het for snow.
If you get Anerys they have a 66% chance of carrying the Albino gene. The Anerys would be Anery 66% possible het for snow.
All of the normals would be 66% "possible double het for snow".
Some of them would be het for Albino. Some would be het for Anery. Some of them would be DH for snow. You can't tell the difference, so they would all be 66% possible DH for snow, since both parents carried both genes. There will also be 1 or 2 that will be completely "normal" and not carry any recessive genes.
If you want to check out other things you might get you can go to www.geneticswizard.com and see what you would come up with. Some people don't like the genetics wizard, but I do. It's fun to see what combinations you can come up with.

Good job Linda! I tutored genetics in college and can't do much better than that, other than to add some stats for ya.
Out of every 16 offspring produced, you will get (again this is like playing the lottery, just the odds):
9 "normal" looking boas
3 albinos, (All 66% possible DHs)
3 Anerys, (All 66% possible DHs)
1 SNOW!
Of the normals, "one" will carry no morph alleles, 2 will be Het for albino, 2 will be het for anery, and 4 will be double hets! So, since 4/9 should "be" double hets, they are technically "Normals 44% possible DH for snow"! Which is a pretty lame stat, but there you go! :'( Enjoy!
